Important Information

+ Box included
🔌 Requires a 9V DC Negative Tip Power Supply or 9V Battery.

The Electro-Harmonix Octave Multiplexer is a classic analogue sub-octave effects pedal designed to add massive low-end weight and synth-like textures to guitar and bass. Using a pure analogue frequency divider circuit, it generates a powerful octave-down signal that tracks best with clean, single-note playing and delivers a raw, vintage character. Favoured for its thick, unmistakable sound, it suits funk, doom, stoner, experimental, and studio layering applications particularly well.
